yBe it known that I, DvI'D F. BAKER, a citizen of the United States, residing at' Dun-y dee, in the county ofYarnhill and State .of Oregon, have invented a newand' useful Shinjgle-lVIa'chi'fe, of which' the following isa speci- .ficatio'nl This invention relates' to machines for nian'j' chines of thatl general class in which a block or.y blocks of wood; are fed toward aI plurality of. revolving knives by providing: Ineans'vfor placing" fresh blocks of wood in position while the cuttes are working and by providing lneans for accurately adjustingthe positions of the knives and the block-guides by which alternate knives being inclined' in' opposite" thef blocks are supportedlin advance of the knives"..,.... n ,i

A stillfurtfher object of the invention' Iis to provide a shingle-machineincluding a blockfeeding nieehanisin and a plurality` of knives,

directions, respectively, in' order. that the butt.. or thieker. edgefof the' shingleniay be cut from one edge of the block and then frorn thehpposa hdfgehf th-e'hlhhh. l

j'webbed spokes23, andt tothe outer portion'l fof this central' disk secured an'. anrnilar` knife-.carrier .25, theA inner edg'e .f'gWhich IOO provided with an anniilar flange 26, fitting v l over' flange l22ar1d secured' thereto'by boltsor 26and- 27 are connected byua web 28,.'tha'tf'is arranged', soine distance` below the ltopfloffl,k the 1 Oneach-of the flanges 26 and 27lv a small vertically-extending flange 30, and these flanges are each cut away to form recesses for the reception of the opposite ends 3l and 32 of the cutting-knives 33, the end 5 portions of the knives being reduced in width so that the length of the blade proper will occupy the full space between the two flanges and the opposite end portions thereof will -bear against the inner faces of the llanges. 1o The inner end of each knife passes under a strap 34, that is rigidly secured in place, and the outer end passes under a strap 35, one end of which is pivoted at 36, while the'opposite end is held in place by a bolt 37. By removing this latter bolt the strap 35 may bef swung outward and the inner end of the knife may be withdrawn from under the strap 34.

It will be' seen on reference to Fig. 3 that zo four knives are used in the present instance, and these knives are all so arranged that their cutting edges fall on non-radial lines. In one pair of diametrically-opposed knives the advance cutting ends are adjacent the inner c 5 flange 26, 'while the advance ends of the opposite pair of cutting-knives are adjacent the outer flanges 27. As the result of this the shear cuts from the block will be first in one direction and then in the opposite direc- 3o tion as the knives successively engage with said block and liability of splitting is materially reduced;

The knives are fixed, and adjustment as to thickness of cut and the bevel or angle of the 3 5 article manufactured are accomplished by providing suitable adjusting mechanisms for the supports between the knives on which the blocks rest between cutting operations. Between each two knives is arranged a seg- 40 mental frame or plate 40, that is provided with a plurality of slots 4l for the passage of ybolts 42, by which said frame is secured to an upper plate 43, that is adjustable circumferentially of the cutter-carrier, the slots permitting such adjustment and the bolts serving to lock the plate in adjusted position, so that the' distance between the end of the plate and the cutting edge of the knife may be accurately adjusted. The block to be 5o cut rests on this plate 43, and if the top of theplate is in parallel relation with the cutting edge a strip of uniform thickness will be cut from the block. It is desirable, however, in the cutting of shingles to adjust the plate to a position at a slight angle to the cutting edge of the knife, so that the space between the two will correspond to the shape of the shingle. To effect this adjustment, the-web 28 is provided with bearing-openings for the 6o passage of two short shafts 44 and 45, that are held from longitudinal movement, and on said shafts are formed screwthreads which engage with threaded openings in the frame 40.

The shafts extend below the web 28 and are provided with bevel-gears 47 and 48, respectively, and with these bevel-gears engage bevel-gears 49 and 50, both of which are mounted on a shaft 5l, adapted to suitable bearings depending from the carrier. rllhe bevel-gears 47 and 4.() are constantly in mesh, said gear 48 being held to the shaft by a feather 52 and being pressed into engagement with the gear 48 by a spring 53, coiled around the shaft and having one end bearing against a pin 54, projecting from said shaft. The opposite gear 50 is rigid on the shaft and is so arranged that when the shaft is pulled outward by means of its operating-handle 55 the gear 50 will be disconnected from the gear 48, while the gears 47 and 49 will remain in mesh and may be turned withou t turning the gear 48. It will be seen that if all ofthe gears are meshing and handle 55 is turned the frame 40 will be moved up and will be maintained in parallel relation with. the edge of the knife, and during the first adjustment ofthe parts all the gears are held in mesh and xthe fra'me 40 is moved either up or down until. 'it arrives at the proper level. If the article to be out is to be thicker at one edge than at the other, the handle 55 is pulled outward and 5() is moved from mesh with the gear 48, 'while on further turning of the shaft the gear 47 will be turned and the outer edge of the frame 40 will be further raised or lowered, as 'Idesired. It will be seen on reference to Fig. 2 that this adjustment has been accomplished by lowering the outer edges of the frames.'

In order to adjust the plate 43 circumferentially of the cutter-earrier, one end of the plate is provided with a depending lug 60, having a threaded opening for the reception of a threaded shaft 61, that passes through a suitable lug 62 of the frame 50. This shaft is provided with a bevel-gear 63, intermeshing with a gear 64 on a shaft 65, that extends to the outer edge of the frame and is provided 'with an operating-handle 66. By turning this handle the supporting-plate 43 may be moved toward or from its cutter.

Owing to the necessity for frequent sharpening of the knives, it is diflieult to secure the necessary parallelism between the cutting edge of the knife and the adjacent end of the plate 43, and to compensate for this wearing away of the knife an auxiliary segmental plate 67 is arranged in a recess formed in the upper face of the plate 43, the upper surfaces of the two plates being flush. The plate (i7 is provided with a rearwardly-extending arm 68, extending through a suitable opening (if) on the plate 43, and to said arm is pivoted a nut 70, arranged for the reception of a screw 7-1, that extends to the outer edge of the frame and is. provided with an operating-handle 72. By turning this handle the edge of the segmental plate 67 may be adjusted into parallel relation with the cutting edge, and thus compensate for the wearing away of the cut- IOO ISO

.se-ms a ter from the grinding and sharpening operations. l

Extending around the cutter is aV circular casing 80, at the topof which is secured the outer edge of an annular plate 81, the inner edge of which is secured in an annular groove at the eriphery vof a disk 82, having a central hu 183, through which the shaft extends- Extending from this hub member' is a series of shortradial ribs 84, to a number of which are connected adjustablesus er1-sionrods 85, the upper ends of theilatter "eing secured to the cross-beam or'frame' 19". Bolted or otherwise secured to the ribs 84 are radial ribs 86",and to the lower' edges of these are bolted angle-bars` 87'.- The" annular` coverplate 81 is formed of segments that 'are'v bolted to angle-bars 87,' and one of these seg- .K ments, together'*Wi-thy a corresponding pfortion of the outer casingjSO, lis ivoted on a-pin 90, carried by al suitable' brac (et 91, projecting from one of the ribs,` so' that the yhollow section may be swung outward, as shown in Fig. 2 to permit access to the knivesand the various devices for adju-'sting1 the positions of the blockrests. `When sWu-ng back linto place, the inner edge of thecover-segm'ent fits Within the annular groove at theperiphery' of the disk 82 and is fartly. confined in place by a clip 92, a `num er o1.- b'ol-ts bei-ng preferably added between-the* iiree'fend ot the'segment and the adjacent angle-'bar 87 in order l toy firmly hold said segment-in place.

Eachot the segments' isprovided with1l a block-carrier and withv an opening'throufgh which a-bl'ockmay lne-inserted and held? in the path of movement of theknives.. Each opening 93 may b e'closed1 by `a-sli'dable cover-plate 94,1thef edges ofwhichl 'iit Within suitable I uselin properly adjusting the position ofthe guides 95,. secured to the upper face of the segment,A and these covers aremoved to andy roby handled levers296, pivote'd' at theirinner ends to the angle-bars andE connected by links 97- tobrackets 98, projecting from the rear 'edges of the-covers. OnE topiv of each cover' is arranged' anadjustable -guiding orv center-ingv strip 995, Which may be' adjusted With respe'ctto: the cover andf locked inf posi*- tion by suitablethumb-screWs-PO0 or other securingv devices.v yThis guide is intended for block being cut withy respect tothe' knives,

Arranged above each segment isl-"ar'vertically-disposed? post orstandard 105; that-is provided withL suitable*-supportsLibr-a vertie cally-arranged cylinder 106, containing a piston 107 and to the piston is secured a rod 10B, that extends out through the upper end oi the cylinder and is secured to the upper end of a presser-barl 109, that extends through suitable guides carried by a stationary ring 109.- Thel upper and lower ends oi the cylinder are connected by pipes 110to a casing containing a valve 112', and said casing is also' in communication With al huid-pressuresupply pipe 113, through Which steam, air,

or' other fluid under pressure' may be'forced.

rlhe stem of the valve 1 12 is provided With an adjusting operating-lever 1 14, carrying a spring 115, Which" rests irictionally against `a may' be adjusted bymeans of a screw 117. This lever may be'adjusted to any position'for the purpose of controllingv4 the iiow of the fluid toeither' end of the cylinder and the exhaust from' thel opposite end' and to increase or decreasethe effective area of the inlet-port in accordance with the pressure to' be exerted on the block. When so adjusted, thespring 115, bearing against segment 116-, Willhold the' lever in position. v

j Secured to each segment at a-point adjacent to the rearWall of the opening therein is a standard 120, against which the rear face of the'presser-ba-r' 109 slides, and to said presserbaris secured a guide-plate 121',- the opposite edges of which are bent to embrace the' edges 8o rigid segment 116,A and the stressof thespring of thestandard The lower end of the l being merely' necessary toturnr the operatinglever 1:14 inorder to' adfmltv the steam' orf air' tothelovverportionof the cylinder 106. `order to` prevent injury to the knives or presser`bar,v the' rear face' of the' latter isprovided with abracket 129, 'carrying an adjustablest'op-in the'form of-.a` screw 180,v that is 'arrangedv tofengage aJ fixed stop 131i, formed at theupperv end oi' the standard 120'. By thisl mean'sgthe'doWnWard movement oithe presser-'foot isfp'osit'ively stopped before the' block-engaging" tongues orfspursy reach the horizontal: pla-ne ot the`cutting-knives.y

' In order lto'takeujgthe strain at the rear Wall of each= opening' 93,r anadju'stable backing-bar 1133l isarranged immediately under eachsegment at a point in vertical alinement W-tli thef rear-'Wall-'of -each'iopening 93; This TOO ` block maybe lifted from cutting position, it

- ends to the bottom of the segment.

bar is provided with curved end members 134, which extend along the side walls of the opening 93 and are secured at their inner The opposite ends of the bar 133 are extended beyond the sides of the opening, and to each end is Secured a vertically-extending screw 135, that passes through unthreaded openings in the segment and in brackets 136 immediately above and carried by said segment. Between the face of the segment and the bracket is a nut 137, surrounding the screw, and by turning this nut in one direction or the other the bar 133 may be raised or lowered to compensate for wear in other parts of the machine, the object being to place the bar as near the horizontal plane of the cutting edges as possible, so that splitting of the wood may be avoided.

In the operation of the machine, the parts having been previously adjusted in accordance with the character of the shingles or other articles to be manufactured, the several covers 94 are moved to closed position, the presser -foot having been previously raised. A block of wood is then placed against the guide 99 on cover 94, and the presser-foot is lowered until the arms or supports 125 are pressed firmly into the top of the block. The lever 126 is then depressed, and the tongue 127 is driven into the block with sufficient force to grip and hold the l block in case the latter is to be raised. The

cover is then moved from place, and the block is .forced down into the path of the knives. As the knife-carrier revolves, each knife will act on each block once during each revolution, and in the machine illustrated, where four knives are employed in connection with six block-holders, a single revolution of the machine will result in the production of twenty-four shingles or similar articles.
